1.1 List of abbreviations for registers
The following abbreviations are used in register descriptions:
read/write (rw)
read-only (r)
write-only (w)
read/clear (rc_w1)
read/clear (rc_w0)
read/clear by read
(rc_r)
read/set (rs)
read-only write
trigger (rt_w)
toggle (t)
Reserved (Res.)
Software can read and write to these bits.
Software can only read these bits.
Software can only write to this bit. Reading the bit returns the reset
value.
Software can read as well as clear this bit by writing 1. Writing ‘0’ has
no effect on the bit value.
Software can read as well as clear this bit by writing 0. Writing ‘1’ has
no effect on the bit value.
Software can read this bit. Reading this bit automatically clears it to ‘0’.
Writing ‘0’ has no effect on the bit value.
Software can read as well as set this bit. Writing ‘0’ has no effect on the
bit value.
Software can read this bit. Writing ‘0’ or ‘1’ triggers an event but has no
effect on the bit value.
Software can only toggle this bit by writing ‘1’. Writing ‘0’ has no effect.
Reserved bit, must be kept at reset value.
